To all whom, it may concern:

Be it known that I, ALFRED MAnsHALL, printer and gold-blocker, a subjectof the King of Great Britain, residing at 36 Friar Lane, Leicester, inthe county of Leicester, England, have invented certain new and usefulImprovements in or Relating to Presses, of which the following is aspecification.

This invention relates to presses such as are used in gold blocking orembossing i. 6., printing in gold, silver, and the like letters anddesigns such as are used on the top bands and socks of boots and shoesand upon the bindings of books, hat sweat-bands, and labels for crownsof hats and for other purposes hereinafter referred to as the work.

In machines as at present employed the chase, which carries the type ordesign, is furnished with a handle by which the operator inserts it byhand into the fire-box and removes it therefrom at each blockingoperation. I

In a press constructed according to this invention a carrier for thechase is provided which obviates the frequent handling in the mannerhereinbefore mentioned of the chase and the loss of time incidentthereto, and this carrier may be of a somewhat different con.-struction, according to the type of press to which it is applied.

According to one form of press a track or carrier for the chase isprovided, so that the chase may be slid along into a position-intoalinement with the gold or other leaf (hereinafter referred to asgold-leaf) to be trans.

ferred to the work, or instead of being slid the chase may be connectedto a carrier, so that it can be swung into position to receive Thepileor sheets of gold-leaf the gold-leaf. to be applied to the face ofthe chase may be supported on a table having a universal adjustment inrelation to the chase.

The invention will be more clearly under{ stood from the followingdescription, in which reference is made to the accompanying drawings.

Figure 1 is a front view of a complete press constructed according toone form of this inf ventlon, and Fig. 2 is an end view of the same.Fig. 3 shows a plan. of the feed-table for carrying the gold-leaf andits supports. Fig. 4 is a section on the line a b of Fig. 2 through thefire-box, showing the manner in which it is supported; and Fig. 5 is anunder side view of the head of the press from which the fire-box issupported. Fig. 6 shows the arrangement of the oil-pad. Fi 's. 7 and Sare a plan and vertical section, respectively, of the platen andfrisket-fingers Figs. 9 and 10 are similar views to Figs. 1 and 2 of amodified arrangen'ient; and Figs. 11 and 12 show in end view and plan,respectively, a further method of supporting and operating the chase.

Like parts are designated by similar reference-numerals in all thefigures, and Figs. A to 8 are drawn to a larger scale than the otherfigures.

In the drawings, 5 is the chase, which carries the die 2, the face ofwhich is supplied with gold or other leaf without the chase beingremoved from the press for that purpose,- and for brevitys sake both thechase and the die are hereinafter referred to as the chase.

3 is a feed-table carried by the machine and adapted to support the pileof sheets of gold or other leaf between which table 8 and the lire-boxthe chase is adapted to be rowiprocated, and 4 is the platen, which isadapter to be moved and pressed up against the chase,

so that the work carried thereon may receive the impressions and leaffrom the heated chase.

The type or die 2 is located in and carrled by the chase 5, in which itis securely held in its correct position relatively to the platen i bymeans of a screw 5*, Fig. 1, in the wellknown manner. The chase 5 issupported from the fire-box 6 by having its upper surface grooved orrecessed to adapt it to engage the said fire-box, and also a carrier,track, or race projecting laterally therefrom along whi ch it is recprocated, as herenafter described. The chase 5 is held in place, so asto have a sl, ding fit on the track by means of overhang'ng metal strips5 Fig. 2, attached one at each side thereof by screws 5 The fire-box 6,by which the chase F s heated, is 2 supported from the head 7 of the man frame 7 of the press by spiral springs, here nafter referred to. Forth' s purpose the rpper surface of the sad fire-box ,s provided w thupstanding studs 9, and in fitt ng the fire-box 11 postion these studsare passed through corresponding holes in the head 7 and provided eachw. th a sp'ral spr ng 8 and a nut 10. The said firebox i s formed withchambers to recelve the perforated gas-pipes 11 or other sui table meansfor heat ng the same. The adjustment of the chase rclat'vely to theplaten is effected by means of the sa, d spr. and nuts aforesad and alsoby means of wedges 12, Fig. 4. The said wedges 12 are located in tapergrooves 13, formed in the under surface of the said head 7- and bearagainst the upper surface of the fire-box 6.

The wedges are forced in by means of screws 14 or in any otherwell-known manner and their action is opposite to that of the sprfngs 8.The said carrier track or race consists of a longitudinal metal plate15, which, in the form shown most clearly in Figs. 1 and 4, is

cast integrally with the fire-box 6 and proj ects laterally horizontallytherefrom. The longitudinal edges are trued .so'as to form an evensurface for the chase 5 to slide on, as

15 above described. The chase may be moved along this race or track bythe hand of the operator to the point where it receives the gold orother leaf from the table 3 and back to the fire-box 6, and vice versa,or mechan- 2o ism may be employed for that purpose. Ac cording to onearrangement the reciprocating movement of the chase 5 is obtainedthrough intermediate mechanism from a foot pedal or lever (not shown)and a spring 25. For this 2 5 purpose a bell-crank lever is-employed,one arm 16 of which is connected by a rod 17, reaching down to the saidfoot-pedal. The other arm 18 of the bell-crank lever has formed on itsfree end a cam edge 18 which bears edgewise against the adjacent curvedarm 19 of a second lever, the other arm 20 of which projects upwardtoward the chase 5 and is connected by a link 21 to a pin 22, projectingfrom the said chase.

lever 16 18 and the second lever 19 20 are each mounted on pivots 16 19respectively, supported by a bracket 23, bolted to'the ma n frame of thepress. The arm 18 is prevented moving laterally relatively to the edgeof the curved arm 19 by means of two plates 24, bolted or otherwisesecured one on each face of the said curved arm 19. The edges of theplates 24 project beyond the edge of the arm 19, so as to form a guidefor the cam edge of the said arm 18 of the bell-crank lever. It will beseen that on depressing the foot-pedal so as to lower the rod 17, andhence the arm 16 of the bell-crank lever, the end of the arm 18 will, asit moves to the right, slide along the curved edge of the arm 19 and indoing so will move the said arm 19 to the right also and its oppositearm 20, connected to the chase 5, to the left, thus eflecting theoutward movement of the. chase from the firebox to 5 5 the feed-table.The return motion of the lever 19 20, and therefore of the chase, to thefire-box is effected by the spring 25, attached at one end to anintermediate point in the arm 20 and at the other end to the frameworkof the press. The chase during its travel along the track or carrier 15and before it comes opposite the table 3 makes a rubbing contact with anoiling-pad, which greases the surface of the same, and thereby enablesit to pick up and retain the gold-leaf with more The bell-crank stmcertainty than if such surface had not been greased.

The chase as it comes opposite the oilingpad raises the latterautomatically, so as to make contact therewith, after which the paddrops down of its own weight out of the path of the chase as the latterreturns from the gold-leaf table 3. The upward movement of theoiling-pad is effected upon the outward motion of the chase alongthetrack 15, as will be hereinafter pointed out. 7

The oiling-pad 26 is carried by an arm 27, Figs. 2 and 6, hinged at 27to the lower extremity of a bracket 28, secured by screws or the like tothe track 15. Between the pad 26 and the hinge 27 a the arm 27 isprovided with an upstanding lifting-plate 29, the upper end of which isreduced to pass through a hole in the upper portion of the bracket 28and carries a nut or equivalent 30, forming a stop. The saidlifting-plate is slotted to carry a lug 31, and the pad is raised bymeans of a hinged cam-piece 32, Fig. 1, carried by the forward end ofthe chase, engaging and lifting the said lug 31 as the chase passesalong. The extent of the upward movement of the pad may be adjusted byaltering the position of the said lug 31 in its slot by means of the nut33, as shown in Fig. 6. to and fro along the track 15 are limited by astop 34 on the said carrier in the outward di rection and by thefire-box in the return direction.

The pile of sheets of gold or other leaf is supported upon thefeed-table 3, which comprises an open box or framing 3, the floor ofwhich consists of two wedge-shaped blocks 35 37, oppositely disposed.The movement of the lower block 35in one direction, by the turning ofthe adjusting-screw 36 or other well-known means, raises the upper block37, upon which the gold-leaf is carried, so that notwithstanding thereduction in the height of the pile of sheets, due to their being takenone by one by the chase, the top sheet is always maintained capable ofmaking contact with or is raised sufficiently high to meet the chase.The said feed-table is arranged to have a universal adjustmenti. (2., itis adjustable in transverse, lateral, and vertical directions to insurethe gold-leaf coming into contact with the whole surface of the chasewhen the operator raises the table or its supporting-rod by hand forthat purpose.

The transverse direction of adjustment is effected by mounting the tableupon a transverse rod 38, supported at one end by a standard 11,projecting laterally from one end of the press, the said feed-tablebeing provided at its under side with a socket 39,'whi ch is squared toengage a similar squared portion of the rod 38. The table when adjustedto its required position on this rod 1S locked, so far as transverseadjustment is concerned, by a set-screw 40. The lateral adjustment Themovements of the chase ICC IIO

of the table is obtained by mounting the rod 38 on thelaterallyprojecting standard 41 by a socket connection, so that t may beslid therealong. and locked in any desired positi on by means of athumb-nut 42, which engages a thread on the reduced outer end of thesaid standardand bears against the sock- '41 to raise-the table up tothe chase.

eted extremity of the rod 38. A spring 43, embracing a reduced portionof the standard, normally forces tne rod 38 toward the outer end of thestandard and permits of the said rod 38 beinglturned about the standqaide said standard is carried by a bracket 41", bolted to the framework 7of the press and provided with a vertical slot, so that the bolts 41 onbeing loosened permit the said bracket and standard and hence the rod 38and table 3 to be adjusted in a vertical direction.

The gold-leaf table 3 normally rests on a stop 45, carried by one end 01an arm 46, the

other end of which screws into and is carried by one end of the frame ofthe press.

The platen 4, Figs. 2, 7, and 8, upon which the work to be blocked orembossed is placed, is fulcrumed at 47 to the framework, so as to movein an arc of a circle relatively to the chase. This platen may be raisedup to the chase by any suitable mechanism; but a convenient'arrangementconsists of toggle-levers 48 49, operated by a hand-wheel 50. Thetoggle-lever 49 is secured at one end to the spindle 54 of thehand-wheel, and at the other end it is hinged to the adjacent end of theother toggle-lever 48, whose opposite end is pivoted to the under sideof the platen. The hand-wheel 50 is provided on its periphery with astud 51, adapted to come in contact witha stop 52 when the toggles arein line with one another and full force thereby contained. The stop 52is bolted to the table or bed upon which the press is supported.

. On the face of the platen is a pair of frisketfingers 55 orequivalent, Figs. 7 and 8 under which the work to be embossed or blockedis held, and these fingers are caused to press upon the work and hold itin position on the platen 4 as the latter rises to the chase, and thusprevent the work shifting as the platen becomes more inclined. Onemethod of effecting this is by. attaching to the slotted base-strip 56,to which the said fingers are adjustably secured by thumb-screws 57, atail or extension 58, which contacts with a projection 59, bolted to theframe 7 of the press, and forces the fingers 55 down onto the work asthe platen r'ses. The said basestrip 56 is pivoted at 60 to anintermediate point in the under part 01 the platen.

The operation of the press is as follows: A pile of sheets of gold orother leaf having been placed upon the feed-table 3, one operatordepresses the foot-pedal, which, through the medium of the rod 17 andlevers 16 18 and 19 20, causes the chase to be moved outward away fromthe fire-box along the track 15, passing in contact with the oiling-padand finally coming to rest in a position in alinement with thefeed-table 3. The same operator now raises the table by hand up to thechase by means of the projecting outer end of the rod 38, soas to feedthe gold or other leaf to the surface 2 of the chase. During thisoperation a second operator places the work to be embossed on the platen4 beneath the frisket-fingers, and by the time this is accomplished thefirst operator has released the foot-pedal, whereupon the spring 25returns the chase to the firebox. The second operator now rotates thehand-wheel 50, thus raising the platen up against the chase with more orless pressure, with the result that the work carried thereon is embossedor blocked ac cording to the design of the die 2.

In an alternative arrangement (shown in Figs. 9 and 10) the chase whenmoved outward into alinement with the table 3 is adapted to be swungdown onto the said table instead of the latter being raised up to meetit, as above described. For this purpose the track preferably comprisestwo horizontal bars 66, Figs. 9 and 10, supported at one end bya bracket67, carried at the outer end of a horizontal stay 68, proj ectinglaterally from the framework 7, into which its other end is screwed orotherwise securely fixed thereto. The chase is supported on thetrack-bars 65 66 by means of split lugs 69, arranged, say, two on oneside of the chase and one on the other side. At a point 65 on thetrack-bar 65 opposite the table 3 the diameter of the bar is reduced, sothat when the chase is moved along the track by the means and in themanner substantially as described the single split lug 69 on that sidethe chase when it reaches the re duced part 65 of the bar 65 allows thesaid chase to swing down onto the'table 3, the other bar 66 acting as apivot or hinge, as shown in broken lines in Fig. 10. When it is desiredto move the chase altogether from the track, it must be moved farther tothe left, Fig. 9, until the split lugs 69 on the other side of the saidchase reach the reduced portions 66 of the bar 66, on which they ride,when the whole chase may be removed. The universal adjustment of thetable is the same in this construction as hereinbefore described.

Figs. 11 and 12 illustrate a further method of supporting and operatingthe chase. In this arrangement the chase is rigidly connected to orformed integral with an arm or carrier 70, so that it can be swungthereby into position to receive the gold-leaf. To effect this purpose,the said carrier is pivoted at its free end on a pin 71, carried by abracket '72, bolted to the framework 7 of the press, as shown. Thearrangement is such that the chase when in the position indicated infull lines in Fig. 12 is in its correct position beneath the fire-boxand above the platen 4. In order to feed the face 2 of the chase withgold or other leaf, the carrier with the chase is swung round on thepivot 71 along the curvilinear path (shown in dotted lines in Fig. 12)until the chase 5 occupies the position shown in dotted lines in thesame figure, where it is in alinement with the feed-table 3. Themovement of the carrier in this latter di rection is limited by a stop73, carried by the bracket 72. The feed-table 3 is now raised by hand,so as to feed a sheet of gold or other leaf to the surface of the chase,after which the latter is swung back until it again occupies theposition beneath the fire-box 6. (Shown in full lines in Fig. 12.) Themovement of the chase in this direction also is limited by a stop 74,carried by the fire-box. The movements of the chase may be facilitatedby means of a handle 75, fitted to the carrier, as shown. Theconstruction and adjustment of the table are the same as that describedfor the press, (illustrated in Figs. 1 and 2,) as are also thearrangement and operation of the platen in relation to the chase.
